Design solution of kitchen furniture due to adjustable positioning fittings. The aim of this diploma thesis is to approach kitchen positioning fittings. The introduction briefly describes the development of kitchen furniture. The next section describes the kitchen parts, kitchen and communication zones. Height distribution of individual work zones with respect to the type of activities performed. Characteristics of kitchen furniture systems. Typology of kitchen furniture, ergonomics and placement of appliances in the kitchen. In the part of the work surface, the coordination dimensions and the height of the worktop are approximated. Different height of the population with respect to the height of work and storage areas. In the main part there is information about available positioning mechanisms for worktops and for upper kitchen cabinets. The main goal of this work is the analysis of positioning mechanisms. Their analysis, display of construction and kinematic schemes. Finally, there is a summary and comparison of the analyzed mechanisms.
